I started reading ham radio magazines, on a monthly basis which came out exctly 50 years ago. This month's issue: The 73 Magazine from June 1970: ia800702.us.archive.org/27/ite

Finally managed to install the antenna switch in the attic. For controlling it remotely, I use an old Arduino with Ethernet shield. Since the antenna switch needs 12V for triggering its relais, a 4 channel relais module is needed to convert the high signal from 5v to 12v. The Arduino takes simple HTTP GET requests for choosing the desired antenna. Now I can switch to any antenna from the shack via the network without a dedicated control cable 👍

Just look at this beautiful hand crafted QSL card! It’s also very special because it confirms my first Hell (rag chew) QSO with a very nice OM. Thank you Eric, F4FAP!

My new Radioddity GD-77 arrived today. After flashing it with OpenGD77 I now can enjoy Brandmeisters Talker Alias feature. Note that no contacts csv is installed on the device.

To those who told me a shortened multiband EndFed wouldn’t be much fun with SSB: I have lots of fun!

Absolute major achievement today: Phonie QSO (SSB) on 20m from Germany to the USA (DL6MHC <-> W1C) with only 20W and a end fed wire antenna! First time for me but I was lucky to be one of the first responding to them calling CQ.

The antenna switch itself is assembled and working. Next step: interfacing the pi and coding a simple web service which will be used to select an antenna via network

New project: raspberry pi controlled remote antenna switch. One remote rpi for triggering the 4 relais inside the antenna switch and one rpi connected to the TRX in the shack measuring the ATU port's voltage to fully automatically choose the correct antenna for each band. Let's see how this works out :)

The DIY 30m dipole made it over the pond 😀 DL6MHC (JN49) --> VO1NC (GN38) via FT8

I successfully moved my logbook to (self-hosted) so I'm finally able to migrate to a Linux desktop in the shack. The following diagram shows how it might look.

blue=local software
yellow=web services
dashed lines=no solution yet

What are your thoughts? How would you log from fldigi and flwkey to Cloudlog?

Had fun last night making a shortened 30m dipole based on the calculations of OE1MEW. If everything goes well, I’ll be QRV on 30m this weekend 😊

The Open CW Keyer is a great little device. Open source hard- and software - like it always should be.

A package just arrived - Looks like I have a little hardware project for tonight :)
